SkyPilot is a framework for running LLMs, AI, and batch jobs on any cloud, offering maximum cost savings, highest GPU availability, and managed execution.

SkyPilot **abstracts away cloud infra burdens**:
- Launch jobs & clusters on any cloud
- Easy scale-out: queue and run many jobs, automatically managed
- Easy access to object stores (S3, GCS, R2)

SkyPilot **maximizes GPU availability for your jobs**:
* Provision in all zones/regions/clouds you have access to ([the _Sky_](https://arxiv.org/abs/2205.07147)), with automatic failover

SkyPilot **cuts your cloud costs**:
* [Managed Spot](https://skypilot.readthedocs.io/en/latest/examples/spot-jobs.html): 3-6x cost savings using spot VMs, with auto-recovery from preemptions
* [Optimizer](https://skypilot.readthedocs.io/en/latest/examples/auto-failover.html): 2x cost savings by auto-picking the cheapest VM/zone/region/cloud
* [Autostop](https://skypilot.readthedocs.io/en/latest/reference/auto-stop.html): hands-free cleanup of idle clusters

SkyPilot supports your existing GPU, TPU, and CPU workloads, with no code changes.

Install with pip (we recommend the nightly build for the latest features or [from source](https://skypilot.readthedocs.io/en/latest/getting-started/installation.html)):
```bash
pip install "skypilot-nightly[aws,gcp,azure,oci,lambda,runpod,fluidstack,cudo,ibm,scp,kubernetes]"  # choose your clouds
```
To get the last release, use:
```bash
pip install -U "skypilot[aws,gcp,azure,oci,lambda,runpod,fluidstack,cudo,ibm,scp,kubernetes]"  # choose your clouds
```

Current supported providers (AWS, Azure, GCP, OCI, Lambda Cloud, RunPod, Fluidstack, Cudo, IBM, Samsung, Cloudflare, any Kubernetes cluster):

## Getting Started
You can find our documentation [here](https://skypilot.readthedocs.io/en/latest/).
- [Installation](https://skypilot.readthedocs.io/en/latest/getting-started/installation.html)
- [Quickstart](https://skypilot.readthedocs.io/en/latest/getting-started/quickstart.html)
- [CLI reference](https://skypilot.readthedocs.io/en/latest/reference/cli.html)

## SkyPilot in 1 Minute

A SkyPilot task specifies: resource requirements, data to be synced, setup commands, and the task commands.

Once written in this [**unified interface**](https://skypilot.readthedocs.io/en/latest/reference/yaml-spec.html) (YAML or Python API), the task can be launched on any available cloud.  This avoids vendor lock-in, and allows easily moving jobs to a different provider.

Paste the following into a file `my_task.yaml`:

```yaml
resources:
  accelerators: V100:1  # 1x NVIDIA V100 GPU

num_nodes: 1  # Number of VMs to launch

# Working directory (optional) containing the project codebase.
# Its contents are synced to ~/sky_workdir/ on the cluster.
workdir: ~/torch_examples

# Commands to be run before executing the job.
# Typical use: pip install -r requirements.txt, git clone, etc.
setup: |
  pip install "torch<2.2" torchvision --index-url https://download.pytorch.org/whl/cu121

# Commands to run as a job.
# Typical use: launch the main program.
run: |
  cd mnist
  python main.py --epochs 1
```

Prepare the workdir by cloning:
```bash
git clone https://github.com/pytorch/examples.git ~/torch_examples
```

Launch with `sky launch` (note: [access to GPU instances](https://skypilot.readthedocs.io/en/latest/cloud-setup/quota.html) is needed for this example):
```bash
sky launch my_task.yaml
```

SkyPilot then performs the heavy-lifting for you, including:
1. Find the lowest priced VM instance type across different clouds
2. Provision the VM, with auto-failover if the cloud returned capacity errors
3. Sync the local `workdir` to the VM
4. Run the task's `setup` commands to prepare the VM for running the task
5. Run the task's `run` commands
